Description
Details and engineering challenges of the Compact X-Ray Light Source (CXLS) at ASU are described. The CXLS achieves x-ray photons with energies in the range of 6-20 keV by using Inverse Compton Scattering (ICS) where the electron beam interacts with a powerful laser instead of the traditional magnetic undulator. The short wavelength of the laser relative to a magnetic undulator reduces the electron beam energy required to produce hard x-rays. Since magnets are not used for undulation, as in traditional large light sources, the accelerator vault of the CXLS is only 10 m long. This extremely compact size allows the entire facility to fit into a university building and to be built at a fraction of the cost of other bright sources of femtosecond x-ray pulses. We review CXLS design elements and then describe operations experience and equipment upgrades with a focus on the photoinjector laser and the ICS interaction point chamber and its associated controls and beam diagnostics.
